Description
Technical field
The present invention relates to a kind ofly, belong to the mechanical processing technique field about decorating with surface treatment of edge sealing bar and process for surface modification scheme.
Background technology
The edge sealing bar is to be main raw material with the polyvinyl chloride, adds auxiliary agents such as softening agent, stablizer, lubricant, dyestuff, the thermoplastic coiled material that mixing together compacting forms.There are decorative patterns such as wood grain, marble, woven design, pattern in its surface, and surface luster is soft simultaneously, has the sense of reality and the stereoscopic sensation of timber; Have certain smooth finish and ornamental, have certain heat-resisting, chemicals-resistant, erosion resistance, surface certain rigidity is arranged.The major function of edge sealing bar is that the sheet material section is carried out solid envelope, reaches the unfavorable factor of avoiding in environment and the use (being mainly moisture) destruction of sheet material and the formaldehyde of prevention sheet material inside are volatilized, and reaches the effect of decoration simultaneously.The ordinary method of getting up edge sealing bar and plate adhesion is to use the hot melt adhesive of polyurethane adhesive system, and this glue is that price is very expensive, has also increased the cost of furniture.If before bonding the edge sealing bar is carried out surface treatment and surface-treated, then can improve the cementability of low-energy surface base material greatly, thereby can use the hot melt adhesive of common, inexpensive to replace expensive polyurethane adhesive system.
Traditional improvement edge sealing bar comprises with the surface treatment method of figure layer adhesiveproperties: solvent expansion and corona treatment after mechanical grinding, obliterating solvent, acidity or the corrodibility etching.These treatment processs all have limitation, often are applicable to the treatment process of this material and are not suitable for other material, and this just impels people to seek new alternate treatment process.
PRK ultraviolet (UV) radiation provides a kind of new bonding front surface to handle and process for modifying surface.But price is very high, and the excimer laser that with the wavelength is 193nm is an example, and the required gas argon fluoride price of its work is just very high, and safeguards also cumbersome.This patent essence is: replace " Excimer UV laser " and be purpose to improve bonding strength, obtains small-sized and price UV radiant light superficial treatment system appropriate, that Working environment is less demanding.
The hertzian wave of 200-150nm is defined as far ultraviolet radiation.Narrow band (200-180nm) is that the polymer photochemistry modification is feasible and regional efficiently; The energy of light surpasses the intensity of the typical organic polymer chemical bond of great majority, therefore can produce photochemical reaction very effectively.Nearly all organic cpds (except the saturated aliphatic hydrocarbon and fluorocarbon) has strong absorption in this zone.Definite at present, this radiation absorption intensity when penetrating the about 300nm of organic polymer reaches 95%.
Polymkeric substance is observed law of Beer to the absorption of photon.The result shows that a large amount of chemical bond ruptures is arranged in the irradiation range.Usually, the organic molecule irradiation life is the picosecond level in this section wavelength region.The bond rupture of polymer chain often is accompanied by cohesive process again, and therefore the end-result of reaction is to lose little gas molecule (CO, CO
2, H
2) and the degraded that produces of the fracture of polymkeric substance line style structure.
Because the existence of air, oxygen is captured enemy personnel the radical end, initiated oxidation product, further photolysis and producing than small shreds.Prolong irradiation time may command polymer etch.When photoelectron with HS and SP during burst transmissions, the concentration of irradiation range internal fragment generally reaches very high value, when its value of overstepping the extreme limit, causes the spontaneous gas phase (photolysis of melting) that is transmitted into of fragment.
Because the short laser pulse time, in fact do not have heat to cross the border of irradiation zone.Thereby be issued to high precision in the situation that does not have pyrolytic damage.
The bonding front surface processing of Excimer UV laser and the core parameter of process for modifying surface: optical maser wavelength and laser energy.
Optical maser wavelength kind: 170nm, 193nm, 222nm, 248nm, 308nm and 351nm (excimer laser can only have a kind of kind of laser peak wavelength at one time, and ripple is wide very narrow)
Because it is feasible and regional efficiently that the 200-180nm wave band is the polymer photochemistry modification, when the energy intensity of 193nm laser surpassed 6.6eV, the chemical bond of nearly all organic materials directly destroyed (organic bond energy is nearly all less than 6.6eV).
If design and manufacture: the output wave band all has energy intensity in the 200-180nm scope, energy intensity surpasses the UV radiation laser beam of 6.6eV, just can obtain the UV radiation laser beam based on bonding front surface processing and surface-treated.
Deuterium lamp output wave band is in the 160-400nm scope.Mainly " ultraviolet spectrophotometer (beginning) ", be used as light source from 190nm.Just because of this, generally to deuterium lamp output wavelength scope understand from 190nm begin and relative light intensity very a little less than.Main problem is: " response " scope of the photodetector in " ultraviolet spectrophotometer (beginning) " and intensity from 190nm 190nm very a little less than.Rather than deuterium lamp output wave band intensity very weak (like Fig. 1) in the scope of the 190nm left and right sides.
Through to the research document of relevant deuterium lamp output wave segment limit with in the concrete qualitative detection of wave band 200-180nm scope, can confirm: very strong at wave band 200-180nm scope deuterium lamp output energy intensity to deuterium lamp output.
Obtained the light source of " having high-energy " in wave band 200-180nm scope.Then through sophisticated " UV beam split "; Technology such as " shaping of UV radiation laser beam " and " multi beam can superpose "; Just can invent a kind of replacement " Excimer UV laser ", small-sized and price appropriateness, bonding front surface is handled and the UV radiant light superficial treatment system of surface-treated.。
